  1. A8 Archon, Spy vs. Spy, and a whole bunch of others I am probably forgetting.
  2. Well, even before that part, it gives a maximum airspeed over ground of "23 furlongs per fortnight," and an operating environment roughly equivalent to operating 100 feet underwater, lol. EDIT: Shame on me, I did the estimation wrong in my head. Ten atmospheres is about 335 feet deep at standard density of water. Sea water is denser, so it would be shallower. 😛
  3. Yeah. But reading carefully can also bring a hearty chuckle.
  4. Not familiar with that model but if it’s a CRT, please don’t mess around with it unless you *really* know what you’re doing. They can quite literally kill you.
  5. Oh, it was the original. I got my kit of parts put together before the BOM change. Very fortunate I only lost a CF card and the XEL CF2 interface. Everything else was perfectly fine.
  6. That didn't save me from doing the same with my XEL. 😛
  7. Got my Dragonfly Cart today, several days before I expected it, and finally got a chance to hear this one with YM sound on real hardware. I sure hope more homebrew authors will take advance of YM sound in the future 'cause this sounds great.
  8. My Dragonfly just arrived moments ago, hand delivered by my postal carrier. Can’t wait to give it a try tonight. Thanks, Rafal!
  9. About a year and a half ago I was swapping my 1200XL for my 1088XEL at my main retro-desk. I unplugged the 1200XL, set it aside, then moved the XEL into the spot. I reached for the XEL’s 5VDC PSU lead and plugged it in. Except it wasn’t the 5VDC PSU lead I grabbed, it was the 1200XL’s 9VAC lead, which has the same size plug. A quick pop and hilarity ensued. I was very, very lucky that the only thing destroyed was one or more logic chips in my XEL-CF2 CF card interface and the Sandisk 8GB card inside. All of the Atari chips - including both POKEYs, thank Jebus - were good. I used the event as the opportunity to replace the CF2 interface with the improved CF3 version and replaced the dead card and all is well. The XEL power jacks has been changed on the current bill of materials to prevent this but I still haven’t changed the plug and power supply on mine. 👀 I did put a brightly-colored cable wrap on the XEL lead however, to hopefully catch my eye.
  10. Thanks, Thom! When mozzwald has a new build ready, I’ll update and give it a spin.
  11. So there was a topic in the main A8 forum in the last couple days about how to print ATASCII program listings. There are several options of course, including the G: device driver from A.N.A.L.O.G. Computing (Oct 1985), and the FujiNet ATASCII printer setting. I got interested enough that I ran the program from A.N.A.L.O.G. to create the AUTORUN.SYS file that loads the G: driver and read the article that accompanied the program. The driver is sophisticated enough to have several different printing options, including limiting printed output the same margins as the standard Atari 40 column screen. BTW, the G: driver actually works with FujiNet when you set it to "Epson 80" mode. Messing around with the HTML ATASCI driver tonight for comparison, I realized that long program lines extend past the usual 80 columns available to most printers. The HTML output from the driver will open in any browser, and most browsers allow you to "print" that resulting HTML file to a PDF for later use or manipulation, or actual physical printing. However, program lines that extend past the vintage 40 column length, or the modern ~80 columns per page in landscape mode aren't wrapped. So to print a program listing requires either setting your printer to Landscape orientation or else shrinking the scale down to fit, sometimes to as low as 60% or so. It would be a nice enhancement of the HTML printer if the user could set the output margins to something besides the length of the program line. Maybe a toggle to set the page width between 40, 80 and 132 columns? Something to wrap longer lines so they can be printed without running off the edge of the paper and being truncated, or having to be shrunk down in size too small to be legible to older eyes. What does everyone think?
  12. On a lark, I downloaded the ATR, loaded up "G.BAS" and ran it (*), then booted the modified DOS disk created. I then tested it by listing a simple BASIC program using LIST "G:" to my FujiNet which was set to "Epson 80" mode. Seemed to work fine, though it isn't necessary for a FujiNet - you can just use the FujiNet's HTML ATASCII printer mode instead with no need to use the memory reserved by the G: driver. But in case anyone wants a modified Atari DOS 2.5 image pre-created, here you go. This is an enhanced-density DOS 2.5 disk image containing the usual DOS.SYS, DUP.SYS, RAMDISK.COM and the AUTORUN.SYS file that loads the G: driver on boot. (*) I initially tried to run the program with Altirra BASIC version 1.57 but it hung for some reason before prompting me to insert the DOS disk to write the AUTORUN.SYS file. I then ran it under Atari BASIC rev C and it worked fine. Ironically, the G: driver file itself loads and seems to work under Altirra BASIC. DOS 2.5 G_Driver.atr
  13. Here’s the article. It’s from ANALOG issue 35. Dunno if a disk image is available. https://archive.org/details/analog-computing-magazine-35/page/n81/mode/2up
  14. The first step of course is a solid cleaning with a good-quality electronics cleaner. Isopropyl is good, but Deoxit is better. Spray some liberally into the connector and then insert/remove a 7800 cart vigorously 6-8 times. Then remove the cart and let the connector dry for a few minutes. Be sure to use a 7800 cart rather than a 2600 cart because 7800 PCBs have additional pins along the edges as compared to 2600 carts. If that’s not enough, you can try disassembling the system to gain close access to the connector. Use something about the size of a toothpick and gently bend the metal connector wipes on the 7800 toward one another. Be very careful with this procedure and don’t break pins or bend them so much that they touch. Inserting a cart will separate them again but if they’re touching, 2600 carts don’t use the outer two pins on either side of the connector and those signals will short one another and screw up the 7800. If all that isn’t enough to help, you may need to either replace the connector or the system. I don’t know if the 7800 cartridge connector is a standard edge connector part that can be bought new but I don’t think so. I’d be happy to be wrong on this.
  15. 17track shows that my Dragonfly has made it to NYC as of today - not bad for standard Polish Post! Hope it makes it through US Customs and on to me in the next weeks or so. I already have my PSU from Amazon so I should be good to go when it arrives.
